Well. It is possible without Spirit. Here it is. It seems to work fine although there are a few things that are there for it to look normal.
-The door glass cannot be transparent, or else you can see the breakable on the other side.
-This cannot be used in a DM map, or CS, as you can only walk through it from one side, because on the other side is the breakable glass for when you open it. It should be fine for HL SP though.
Er.. You don't need to credit me if you happen to use it, unless someone asks how you did it.
Have fun!
good work though. interesting idea.
This is the same as the tutorial in WC 2.0??
